The Victoria State Government is seeking expressions of interest for the primary tunnels contracts for the Melbourne North East Link.
Firms are invited to tender for Melbourne’s North East Link to deliver the AUS$7 to $9bn (£4bn to £5bn) primary package including the construction of tunnels.
In addition, a second package is being advertised to deliver AUS$200M (£110M) early works package, expected to start construction in 2020 after environmental and planning approvals are in place.
The Victoria State Government has said that the procurement process will take 18 months to complete.
According to the project, expressions of interest will help them create a shortlist of potential bidders who will be invited to submit detailed tenders as planning and environment requirements become clear.
The project still needs planning approvals and the Environment Effects Statement (EES) and still needs to go on exhibition for public comment and submissions to an independent panel. This is scheduled to happen mid-2019.
Construction for North East Link is still expected to start in 2020 after the EES process is complete and planning approvals have been received.
